| 4.1.4 | Intranet

One common configuration of a LAN is an intranet. Intranet Web servers differ from public Web servers in that, without the needed permissions and passwords, the public does not have access to an organization's intranet. Intranets are designed to be accessed by users who have access privileges to an organization's internal LAN. Within an intranet, Web servers are installed in the network, and browser technology is used as the common front-end to access information, such as financial data or graphical and text-based data stored on those servers. The addition of an intranet on a network is just one of many application and configuration features that can cause an increase in needed network bandwidth over current levels. Because bandwidth has to be added to the network backbone, network administrators should also consider acquiring robust desktops to get faster access into intranets. New desktops and servers should be outfitted with 10/100-Mbps Ethernet network interface cards (NICs) to provide the most configuration flexibility, thus enabling network administrators to dedicate bandwidth to individual end stations as needed.
